What the Vitamin D Test measures
Your body makes vitamin D when skin is exposed to sunlight and also gets it from some foods and supplements. The liver converts it to 25-hydroxy vitamin D, which is the form measured to assess your vitamin D status.
Why it's done
- Checking for vitamin D deficiency, including in people with limited sun exposure
- Investigating bone or muscle pain, or as part of bone-health assessment
- Monitoring levels while taking vitamin D supplements
How to prepare
No fasting is needed — eat and drink normally. Wear something with sleeves that roll up easily, and keep a list of any medicines you take handy for your phlebotomist.
Understanding your result
Your report shows your level with the reference range. Low levels are common; whether and how much to supplement is a decision for your doctor, since taking too much can also cause problems.
Frequently asked questions
Do I need to fast for a vitamin D test?
